The Littelfuse 0452003.MRSN is a 3A, 125VAC surface mount slow blow fuse from the NANO2 Slo-Blo series. It is designed to withstand inrush currents that would cause fast-acting fuses to open, making it suitable for applications with transient start-up loads. The fuse offers a breaking capacity of 50A at 125VAC and 300A at 32VDC, with a melting I²t of 20.16 A²s.
This fuse is housed in a compact 2-SMD square end block package measuring 6.10mm x 2.69mm x 2.69mm, suitable for high-density surface mount assemblies. It operates over a wide temperature range of -55°C to 125°C and is compliant with RoHS and Halogen Free requirements per the manufacturer datasheet.
Typical applications include notebook PCs, LCD/PDP TVs, power supplies, networking equipment, battery charging circuits, and industrial controls. The fuse is recognized by CSA, METI, and UR agencies.
